17.25.1 Step controller heating
Step controller heating can be set to sequential or binary.
Step contr. heating
Activation levels

Binary steps

Step controller Heating activation levels for sequential control.
For binary control the activation levels are calculated by the controller depending on the
number of steps involved
Start step 1: 10 %
Stop step 1: 5 %
Start step 2: 45 %
Stop step 2: 40 %
Start step 3: 70 %
Stop step 3: 65 %
Start step 4: 95 %
Stop step 4: 90 %
Control parameters. Heater groups is used to calculate activation levels for binary control.
"Hyst." is the switching differential used for each step when running binary control.
Heater groups: 4
Minimum on/off-
time: 60 sec
Hyst.: 0.5 %
17.25.2 Step controller cooling
"Step controller Cooling" can be set to sequential or binary.
Step contr. cooling
Sequential

"Step controller Cooling" activation levels for sequential control.
For binary control the activation levels are calculated by the controller depending on the
number of steps involved
Start step 1: 10 %
Stop step 1: 5 %
Start step 2: 50 %
Stop step 2: 45 %

Control parameters. Chiller groups is used to calculate activation levels for binary control.
“Hyst.” is the switching differential used for each step when running binary control.
